I'm personally a little dissapointed that they've (apparently) caved to the card slot cry-bullies. But. I understand why they thought they had to.
Well, it was not very difficult to predict, cry-bullies or not. The 5D bodies have dual slots after all.
my thoughts too. Current R feels like 3fps in servo. I would take 8 fps or better in servo.
The M6II does 14 fps with full servo AF (although "focus priority" mode is 7 fps). I think there's little reason to expect less than 10 fps. This newest generation of Canon tech packs some serious oompf.
